STOCK-RACK FOR PLATFORM-SCALES.

SPECIFICATION forming part of Letters Patent No. 703,586, dated July 1, 1 902.

\ Application filed March 22, 1902. Serial No. 99 ,454- (No model.)

To all whom it may concern; 7

' Be it known that I, CHARLEs'B. HURsT, a citizen of the United States, residing at Chillicothe, in the county of Rossj and State of. Ohio, have invented certain new and'useful Improvements in Stock-Racks for Platform- Scales, of which the following is a specificaa tion.

My invention relates to improvements in stock-racks for platform-scales; and the object of. myinvention is to provide arack that need not be removed from the scale, but is so constructed that it may be folded back, soas to give room for loaded vehicles, such as loads of hay; and my invention more especially relates to means'for adjusting and holding the several parts in'their closed and open positions. 1

My invention consists in the constructions and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure l is a perspective view of a platform-scale with a stockrack embodying my invention. Fig. 2 is a detail showing the adjustable hasp. Fig. 3 is a detail of thehinge, partlyin section, show- 7 ing it extending through one end of the hasp.

Fig. 4 shows the bearing on the upright for the cross-bar. Fig. 5 shows a cross-bar journaled on said bearing. Fig. 6 shows the engagement of the loop at the other end of the cross-bar; Fig. 7 ,the preferred form of engagingand holding the loop, and Fig: Sis a modification showing a cam-latch.

Like parts are represented by similar letters of reference in the several views.

In the drawings the respective side frames, consisting of the uprights b and the longi tudinal slats b, connecting same, are attached to the platform a of the scales, preferably by the ordinary form of strap-hinges b one end of which is fastened to the uprights]? on its inner side adjacent to its lower end andthe other end extending through the platform and one end of ahasp, to be hereinafter described, and is securely bolted thereto, as shown in Figs. 2 and 3. The lower ends of the uprights b are beveled, as shown in Fig. 2, to permit the side frames to swing outwardly, the distance they will swing being limited by I the angle of these beveled ends, and to pre- -.vent' the side frames from falling inwardly, which'is'material to prevent their being damaged in this way, I provide the hasp, consisting of theend c, securely attached to the bottom of the platform a,.preferably by bolts 0 and one end of the hingesb as hereinbefore described. The other portion 0 of the hasp is screw-threaded at itsupper end and extends through the lug or eyebolt 0 secured to the outer side of the uprightsb, the nuts 0? above said eyebolts forming stops to prevent the side frames from falling inwardly. The end uprights b on opposite sides of the scales are formed at or near their upper ends with the bearings 01, to which one end of the respective cross-bars d is journaled by the straps d, the recesses or shoulders formed by the bearings supporting the bars, the arrangement being such that each bar may be swung parallel with its respective side frame and held there by the loop (i engaging the pin 11. The outer ends of the respective cross-bars are provided with the loops d to engage the opposite uprights b, and to prevent the bars being thrown out of engagement I preferably employthe notch cl to engage said loop, as shown in Fig. 7 but the pin (1 may be used, as shown in Figs. 1 and6. The end gates, consisting of the uprights e and the slats e, are preferably hinged to the opposite side frames, so that when open each may be folded against the'side frame to which it is hinged,

and the shoe e is secured to the platform to catch and hold the gate in its closed-position.

In addition to the hasp with'its nuts, forming with the eyebolta stop to prevent the hinged sides from falling inwardly, this hasp and its connections also form a means to tighten said frames in their closed position, for by tightening the nuts of the-hasps over the'eyebolts or lugs of the side frames said frames will be inclined outwardly, and the operator by throwinghis weight on-the outer end of the end gates will strain the side frames inwardly, so that the loops at the outer ends of the cross-bars may be brought into place under the notches d, and the side frames thus be firmly bound together. -It will be seen my construction is such that by tightening the nuts of the hasps over the lugs the strain may always be adjusted to give suificient tension to firmly bind the side frames together.

In Fig. 8 I have shown a modification in which I employ the cam-latch d pivoted in a recess of the uprights, to catch the loop of the cross-bars. By depressing the handle (1 the movement of the cam-latch is outward against the tension of the adjustable hasp connection, and when the handle is in its lowest position the parts are locked. It is obvious that the cam maybe variously modified, as would readily suggest itself to an ordinary mechanic. Furthermore, the wellknown tendency of a gate to sag and drag at its outer end is overcome by the tightening of the nuts over the eyebolts, for this tilts and lifts the outer ends of the gates and gives them a free movement.

Having thus described my invention, I claim-- 1. The combination with the side frames hinged to the scale-platform, cross-bars connecting said frames, of means connecting said frames and platform adapted to incline and tighten said frames to said cross-bars, substantially as specified.

2. The combination with the side frames hinged to the scale-platform and cross-bars connecting said frames, of means engaging said frames and platform adapted to incline and tighten said frames to said cross-bars in their closed position and to form an adjustable stop for said frames when said crossbars are released, substantially as specified.

3. The combination with the side frames hinged to the scale-platform, the cross-bars connecting the side frames and the end gates hinged to said side frames, of means engaging said side frames and platform adapted to spread and incline the side frames outwardly, thereby tightening them to the cross-bars and lifting the outer ends of the gates, substantially as specified.

4. The combination with the side frames hinged to the scale-platform, lugs on said frames, of hasps, one end of said hasps being secured to said platform, and means on the other end to engage said lugs to tighten said side frames and cross-bars in their closed position, substantially as specified.

6. The combination with the side frames hinged to the scale-platform, lugs on said side frames, cross-bars connecting said side frames, and end gates hinged to said side frames, of hasps, one end of said hasps being secured to said platform, and means on the other end to engage said lugs and spread and incline the side frames outwardly, thereby tightening them to the cross-bars and lifting the outer ends of the gates, substantially as specified.

7. The combination of the side frames hinged to the scale-platform, cross-bars connecting said frames, and means, including a screw threaded connection, between said frames and platform, to form an adjustable stop for said frames, substantially as specified.

8. The combination with the side frames hinged to the platform, an adjustable connection between said frames and platform, the cross-bars, and means to tighten and lock said cross-bars in their closed position against the tension of said adjustable connection, substantially as specified.

In testimony whereof I have hereunto set my hand this 8th day of March, A. D. 1902.

CHARLES B. HURST.
